ID 4.2.3.119 DE (-)-alpha-pinene synthase. AN (-)-alpha-pinene/(-)-camphene synthase. AN (-)-alpha-pinene cyclase. CA (2E)-geranyl diphosphate = (1S,5S)-alpha-pinene + diphosphate. CC -!- Cyclase II of Salvia officinalis (sage) gives about equal parts (-)- CC alpha-pinene, (-)-beta-pinene and (-)-camphene, plus traces of other CC monoterpenoids. CC -!- (3S)-linalyl diphosphate can also be used by the enzyme in preference CC to (3R)-linalyl diphosphate. CC -!- The 4-pro-S hydrogen of geranyl diphosphate is lost. CC -!- The enzyme from Abies grandis (grand fir) gives roughly equal parts CC (-)-alpha-pinene and (-)-beta-pinene. CC -!- However the clone ag11 gave 35% (-)-limonene, 24% (-)-alpha-pinene CC and 20% (-)-beta-phellandrene. CC -!- Synthase I from Pinus taeda (loblolly pine) produces (-)-alpha-pinene CC with traces of (-)-beta-pinene. CC -!- The enzyme from Picea sitchensis (Sika spruce) forms 70% (-)-alpha- CC pinene and 30% (-)-beta-pinene. CC -!- The recombinant PmeTPS1 enzyme from Pseudotsuga menziesii (Douglas CC fir) gave roughly equal proportions of (-)-alpha-pinene and (-)- CC camphene plus traces of other monoterpenoids. CC -!- See also EC 4.2.3.120, EC 4.2.3.117, EC 4.2.3.16 and EC 4.2.3.52. CC -!- Formerly EC 4.1.99.8, EC 4.2.3.14 and EC 4.2.3.n7.
